In the following, specific configurations of the high-frequency electrode 300 and the ultrasonic electrode 400 will be described based on one embodiment.

According to one embodiment, the high frequency electrode 300 is a bipolar RF electrode that includes a positive electrode part 310 and a negative electrode part 320 that are spaced apart from each other, and a current is conducted between the positive electrode part 310 and the negative electrode part 320. There is also. Thereby, the high frequency electrode 300 also includes a positive electrode part 310 and a negative electrode part 320. The positive electrode part 310 and the negative electrode part 320 may be spaced apart from each other by a predetermined distance.

In addition, the ultrasonic electrode 400 is also arranged between the positive electrode part 310 and the negative electrode part 320 of the high frequency electrode 300.

By having the high frequency electrode 300 and the ultrasound electrode 400 arranged as described above, high frequency waves and ultrasound waves can be effectively provided simultaneously to a specific position on the skin.

That is, if the high frequency generation module 120 and the ultrasound generation module 130 operate while the user's body is in contact with the skin contact head 200, the user's body located between the positive electrode part 310 and the negative electrode part 320 of the high frequency electrode 300 A high frequency current is conducted through the site. In addition, since the body part is located under the ultrasound electrode 400, it can be provided with ultrasound. Therefore, the skin management effect can be improved.

According to an embodiment, the positive electrode part 310 and the negative electrode part 320 may each have a crescent shape with a recessed surface R on one side. In addition, the positive electrode part 310 and the negative electrode part 320 may be located on both sides of the skin contact head 200. At this time, the positive electrode part 310 and the negative electrode part 320 are also arranged so that the recessed surfaces R face each other.

In addition, although the ultrasonic electrode 400 is located at the center of the skin contact head 200 and is arranged between the positive electrode part 310 and the negative electrode part 320 of the high-frequency electrode 300, the recessed surface R of the positive electrode part 310 and the negative electrode part It is also arranged between the recessed surface R of 320.

Since the high frequency electrode 300 and the ultrasound electrode 400 have the above-described shape and arrangement, high frequency waves and ultrasound waves can be effectively provided to a specific position on the skin at the same time. That is, the high frequency waves generated at the positive electrode section 310 pass through the skin and are transmitted to the negative electrode section 320. At the same time, ultrasonic waves are provided inside the skin by the ultrasonic electrode 400 on the current passage path. In particular, the recessed surface R of the positive electrode section 310 and the recessed surface R of the negative electrode section 320 face each other, and the ultrasonic electrode 400 is positioned between the recessed surfaces R, so that the high-frequency electrode 300 can generate ultrasonic waves as a whole. The arrangement is such that it surrounds the electrode 400. Therefore, high frequency waves and ultrasound waves can be intensively provided to a specific part of the body located under the ultrasound electrode 400. That is, according to the high frequency and ultrasound paths realized by the shape and arrangement structure of the high frequency electrode 300 and the ultrasound electrode 400 according to one embodiment, the high frequency and ultrasound waves are intensively provided to a specific position on the skin. It can be done. Therefore, the skin management effect can be improved.

According to one embodiment, the skin contact head 200 also includes a cover member 210 that covers at least a portion of the ultrasound electrode 400.

For example, an ultrasound electrode 400 may be fixed to one position of the skin contact head 200, and a cover member 210 covering the ultrasound electrode 400 may be fixed to the skin contact head 200. For example, the skin contact head 200 has a predetermined fitting part 220 that is configured by itself, and the ultrasonic electrode 400 is located in the fitting part 220, so that the ultrasonic electrode 400 may be exposed, and the skin contact head 200 may be fitted into and fixed in the fitting part 220.

According to one embodiment, the cover member 210 covers the ultrasound electrode 400 but also includes a window hole 212 through which at least a portion of the ultrasound electrode 400 can be exposed. The ultrasonic waves provided from the ultrasonic electrode 400 are also transmitted to the user's body via the window hole 212.

By providing the cover member 210 that covers the ultrasound electrode 400 as in this embodiment, the area and intensity of ultrasound provided by the ultrasound electrode 400 can be appropriately adjusted.

Additionally, according to this embodiment, the cover member 210 is replaced, and the area of the window hole 212 can be selectively varied. In this case, the area and intensity of the ultrasound provided by the ultrasound electrode 400 may be appropriately adjusted.

FIG. 5 shows a cross section of a portion covered by the cover member 210. As illustrated in FIG. 5, according to an embodiment of the present invention, the cover member 210 may have a predetermined thickness, and the window hole 212 may have a predetermined depth. In addition, the inner circumferential surface of the window hole 212 is formed by a slope surface 214, and the cross-sectional area of the window hole 212 may be increased toward the outside.

According to this embodiment, the inner circumferential surface of the window hole 212 is also constituted by an inclined surface. Therefore, when using the skin care device according to the present invention with the gel applied to the skin, it is possible to effectively reduce the accumulation of the gel applied to the skin in the window hole 212. In addition, even if gel accumulates inside the window hole 212, it can be easily cleaned and removed from the window hole 212. Therefore, user convenience and hygiene can be improved.

If the inner peripheral surface of the window hole 212 is not a sloped surface as described above, when using the skin care machine with gel applied to the skin, the gel will tend to accumulate in the window hole 212. Difficulties also arise in cleaning the accumulated gel. In this case, even when cleaning with a tool such as a cotton swab, the gel gets stuck in the corners and is difficult to remove by cleaning.

On the other hand, in the skin management device according to the embodiment of the present invention, since the inner circumferential surface of the window hole 212 is constituted by an inclined surface as in the embodiment, it is possible to prevent gel from accumulating in the window hole 212. Even if gel accumulates inside the window hole 212, it can be easily cleaned and removed from the window hole 212.

In particular, in the case of a skin care device that uses ultrasound and high frequency waves, such as the skin care device of the present invention, a predetermined gel (conductive gel) is often applied to the user's skin before use. Therefore, if the cleaning convenience for gels is improved, user convenience and hygiene can be greatly improved.

As another example, the operation mode by the control device may include a second operation mode as shown in FIG. In the second operation mode, one of the high frequency generation module 120 and the ultrasonic generation module 130 operates discontinuously. For example, as shown in FIG. 7, high frequency waves are output continuously, and ultrasonic waves are output and not output alternately. Of course, on the contrary, the ultrasonic waves may be output continuously, and the high frequency waves may be output and not output alternately.

FIG. 8 is a diagram showing waveforms of ultrasonic waves and high-frequency waves generated during operation of a conventional skin care device. Unlike the present invention, prior art skin care machines provide ultrasound and radiofrequency waves sequentially.

Although both the high frequency and the ultrasound waves can provide heat to the skin, there are differences in the actual sensations experienced. The radiofrequency provides a gradual sensation of heat, while the ultrasound provides heat with some tingling. The skin care device according to an embodiment of the present invention may have an operation mode in which ultrasound and high frequency waves are not continuously provided at the same time, but at least one is provided discontinuously; It may have an operating mode in which sound waves and radio frequencies are alternately provided.

For example, the frequency of the high frequency may periodically and repeatedly change to 1 Mhz, 2 Mhz, and 3 Mhz. However, it is not limited to this.

As another example, the operation mode by the control device may include a fourth operation mode, as shown in the lower diagram of FIG. In the fourth mode of operation, the frequency of the ultrasound provided by the ultrasound generation module 130 changes. For example, the frequency of the ultrasound may periodically and repeatedly change from 1.2 Mhz to 2.5 Mhz. However, it is not limited to this.

Although not shown, it is also possible for the first to fourth operation modes to be mixed. That is, at least one of the high frequency generation module 120 and the ultrasonic generation module 130 operates in an on/off state, and the frequency of at least one of the provided high frequency and ultrasonic waves can be varied. It is.
